This paper investigates different systems for atmospheric probing. A portable ultrasonic anemometer, integrated with a GPS, wireless data transmission, and data acquisition systems, is mounted on a quadcopter platform. This configuration provides a mobile measurement unit capable of free movement in the atmosphere, delivering measurements of airspeed, temperature, pressure, humidity, air density, and the system’s physical orientation. In parallel, a ground-based Doppler LIDAR system (WindCube) is used as a reference, providing 20 simultaneous measurements at arbitrarily selected heights between 40 and 300 meters above ground level.
